Abstract This chapter describes a research thread at CITA which explores how computation and a challenging of traditional material practice can impact the use of timber in architectural design and fabrication. Several past research projects at CITA have demonstrated the potential for streamlining the design-to-production process using computational tools, and the value of working in concert with the inherent properties of wood. Current research continues this thread through a participation in the Innochain research network (http://innochain.net/) and collaboration with industrial partners White Arkitekter AB and Blumer-Lehmann AG. Through the embedding of digital tools within established timber design a fabrication processes, new workflows are proposed which could lead to more intelligent design decisions, optimized building components, and new timber morphologies.

1 Introduction 1.1 Background The design, fabrication, and use of free-form timber elements involves many steps: design and CAD, CAE, joinery and detailing, supply and sourcing, fabrication, logistics and assembly, maintenance and durability, and the component lifecycle. Such design and fabrication workflows are typically linear and have little opportunity for mutual informing or recursion between steps. This investigation focuses on how freeform timber elements are designed, how they are fabricated, and how more knowledge of material principles can be embedded into both domains through computational processes and digital sensing tools. Glue-laminated timber beams—glulams—are used as the starting point, due to their use in industry for creating large-scale freeform building elements. The notion of the glulam blank—the raw laminated timber piece that is subsequently machined into the final timber element—is central to the investigation. Exploratory material probes question the typical categorization of glulam blanks into straight, single-curved, or double-curved blanks by proposing new types of blanks based on a variety of production and material principles.
